Answer:
Dimensions:
H = 0.9 m
W = 0.4 M
L = 2.4 m
Step-by-step explanation:
As they are all the same dimensions and there are only 3 stairs, divide all the figures (except the length as it will stay the same) by 3 to get your figures.
I assumed that 3 households are sampled.
Now, is the number in each of these households equal to 1, 3 and 8 people?
Next, the question says, samples of n=2 are randomly selected (with replacement) from these 3.
So are sample space is
11
13
31
33
18
81
38
88
83
88
This is done 9 times.
Is that how you understand the problem?
When they select the household with only 1 person, the variance is 0
When they select the household with 8 people, they variance will be from a discrete uniform distribution
Similarly for household with 3 individuals.
Answer:
$200
Step-by-step explanation:
Consider the original price be x
As per the question
Solving the equation yields:
- ⇒0.7x=140
- ⇒0.7x/0.7=140/0.7
- ⇒x=1400/7
- ⇒x=200
In conclusion
the original price of the jacket was $200
I think that 800000 is already rounded.
